Three possible exogenous variables including perceived certainty of punishment, perceived response cost, and acquiescense are suggested that are based on the protectiom motivation theory. As a result, we found followings. First, The perceived punishment certainty has a significant effect on the perceived importance of information security. Also, it influences a negative effect on acquiescence. Second, the response cost has a negative effect on the perceived importance of information security. In addition, the response cost positively effects on acquiescence. Finally, acquiescence negatively influences on the perceived importance of information security. The results show that, in order to increase the perceived importance of information security among employees, it is necessary to make them aware that a security violation can result in certain punishment. At the same time, organizations should also attempt to remove major obstacles accompanying security behaviors of employees. Finally, organizations encourage open communication relating to information security among employees.

An intrusion detection technique based on host consider system call sequence or system call arguments. These two ways are suitable when system call sequence or order and length of system call arguments are out of order. However, there are two disadvantages which a false positive rate and a false negative rate are high. In this paper we propose the T-N2SCD detection model based on Time Window in order to reduce false positive rate and false negative rate. Data for using this experiment is provided from DARPA. As experimental results, the proposed model showed that the false positive rate and the false negative rate are lowest at an interval of 1000ms than at different intervals.

This paper is analyzed causality using cointegration test and impact response after deriving a causality between direct overseas purchasing and sale and macroeconomic variables. The model used for the empirical analysis is the vector error correlation model. The model is used the macroeconomic variables such as the consumer price index and the GDP, and e-commerce variables such as direct overseas purchasing, direct overseas sales and online shopping amount. According to empirical analysis, the direct overseas purchasing has the causality with the consumer price index, and GDP has the causality with direct overseas purchasing and online. According to the impact response analysis of the VECM, the direct overseas purchasing has a positive effect on the CPI and GDP, but the direct overseas sales has a negative effect on the CPI and GDP. In addition, both direct overseas purchasing and sales have a negative effect on online shopping, but it has been shown that the direct overseas purchasing has a bigger negative effect on online shopping.
